Star, which religion is backed by logic or evidence? All religions are based on the concept that there is a God. No Muslim has seen Allah, No Hindu has seen Bhagavan and no Christian has seen God!
The one unique feature of what can be called the hallmark of 'middle eastern' religions is that they all evolve from the earlier one. There is Judaism which is Judaism, and then there is Christianity which Judaism version II and Islam which is Judaism Version III. Like the Windows OS they are all backward compatible but not forward compatible. Islam possibly realizes that Judaism Version IV could have emerged. To protect against this they say that Mohamed the Prophet was the last Prophet.
For mankind who cannot define what or who is God the concept of religion will remain amorphous!
Logically whatever you say about Hinduism can be true or false! Ironically if you replaced Hinduism with Islam it could be false or true! The same for Christianity or any other denomination.
Ultimately it is matter of faith, if you believe in what you believe in then you believe in it! On a touch stone of logic all religions fail miserably!
